Help with a cover letter

Hello.

I'm writting a cover letter and I need help with this:

I feel motivated when there is are big challenges to be resolved because I like to research and delve for into the problem to reason (problem solve) and developer develop a elegant (I would use reasonable rather than elegant) solution for them.

Is this correct? I'm not using a formal language, can you help me?


Thanks in advanced.

Good job and good luck with the rest of your cover letter! And, as a side note, remember that when using "a" before any word that starts with a vowel, it changes to "an." So when you say "a elegant solution", it should be "an elegant solution."
